Sulphuric acid 96 %, ROTIPURAN®, p.a., ISO, 1 l

Sulphuric acid 96 % is a high-purity mineral acid supplied as ROTIPURAN®, p.a., ISO grade for demanding analytical work. With CAS number 7664-93-9 and empirical formula H₂SO₄, it has a molar mass of 98,08 g/mol and a density of 1,84 g/cm³. The boiling range lies between 295 and 315 °C, supporting controlled heating and digestion procedures in the laboratory. This reagent is packed as 1 l in glass and is intended for environmental analysis, sample preparation, and general acid–base applications where consistent analytical quality is required. The p.a. and ISO specification supports use as a reference-grade acid in quantitative workflows. Offered from manufacturer Carl ROTH under the ROTIPURAN® line, the product combines defined concentration with clear physicochemical data for routine and research settings. Typical uses include wet-chemical digestion, pH adjustment of strongly acidic media, and preparation of standard solutions in analytical chemistry. The glass bottle format suits bench-scale handling of concentrated sulphuric acid in controlled laboratory environments.
